(4) after the most of or whole erosion of refractory material, can lean on the slag crust on the cooling wall keep ordinary production.
Adopt the cast steel cooling wall that two advantages are arranged: the one, eliminated coating thermal resistance, air gap thermal resistance, therefore can significantly improve the comprehensive heat conductivility of cooling wall; The 2nd, the performance indications of cast steel obviously are superior to cast iron, reduce the cooling wall crackle, fall the phenomenon of piece, wearing and tearing.
The manufacturing technology of cast steel cooling wall is mainly at material and process aspect.The material of cooling wall is approaching consistent with the phosphorus content that is cast into water pipe, thereby cast steel and water pipe are better fused into one.Process aspect will take appropriate measures, and guarantees to be cast into water pipe and the good fusion of cast steel, reaches the effect of " molten and do not wear ", and this is that the making difficult point of cast steel cooling wall belongs to.
At present adopt water-cooled mode during the cast steel cooling wall casting and pouring or add the mode of chill.There is following problem in water-cooling pattern: 1. flow, the pressure and other parameters needs during water flowing are groped just can draw as the case may be repeatedly; If water yield control is improper; Will influence the fusion rate between cooling water pipe and the cooling wall body; The heat-sinking capability of water pipe is greatly reduced, can not guarantee the advantage that the cast steel cooling wall thermal conductivity is good; Cooling water will have certain pressure when 2. working, and has potential safety hazard, and working environment is relatively poor; 3. need a cover water system professional equipment, drop into bigger.There is following problem in the mode that adds chill: adds the chill amount and needs detailed calculated, also might influence the body interior quality if too much influence the fusion rate of steel pipe, and the very few effect that does not have the protection cooling water pipe, steel pipe is prone to by burn through.
The utility model content
Cooling water pipe was difficult for by the cast steel cooling wall of burn through when the technical problem that the utility model will solve just provided the casting of a kind of cooling wall.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: comprise the cooling wall body, the cooling wall body is provided with cooling water pipe, is provided with compound cooling medium obturator in the described cooling water pipe, and the mouth of pipe at cooling water pipe two ends is provided with plug.
Its additional technical feature is: described cooling water pipe is the U type; Described every cooling wall body is provided with 3---5 cooling water pipes; The mouth of pipe of said cooling water pipe is stretched in the cooling wall body outward.
When a kind of cast steel cooling wall that the utility model provided is cast, earlier compound cooling medium obturator is poured in the cooling water pipe, then the mouth of pipe at cooling water pipe two ends is used the plug shutoff, again cooling water pipe and cooling wall body are cast into one.Compound cooling medium obturator heat storage capacity is big, and stronger chilling action is arranged, and thermal coefficient of expansion is little; Chemical reaction does not take place in Heat stability is good, does not generate gas; Do not melt adhesion tube wall, easy to clean; Heat with molten steel in the casting process conducts, thereby reduces the temperature of cooling water pipe, and the fusing heat that can satisfy the outer surface of steel tube needs simultaneously again reaches molten and purpose that do not wear.Its advantage is the fusion rate that can guarantee cooling water pipe and cooling wall body, thereby guarantees the cast steel cooling wall capacity of heat transmission, and simple to operate, and no potential safety hazard need not to drop into cooling system, small investment.Casting finishes, and the plug at cooling water pipe two ends is taken off by the mouth of pipe, pours out compound cooling medium obturator and gets final product.As required, cooling water pipe is U type or other shapes, and every cooling wall body is provided with 3---5 cooling water pipes, and the mouth of pipe of cooling water pipe is stretched in the cooling wall body outward, and cooling water pipe adopts seamless steel pipe.
